Can some one post a layout file for: _w{Qtj~s|  
1) dual-fiber collimator, one for input and one for output, with 8 degree angled surface; sx%[=g+<2(  
2) a 8 degree angled GRIN lens (NSG SLW180) 9p/Bh$vJ  
3) a mirror 3Ul*QN{6

Adjust the layout file, thus the output beam return back to the output fiber. !Ee:o"jG{  
r" y.KD^  
The fiber can be SMF-28 corning fiber. >

This is a very often used dual-fiber collimation for Telecom fiber optics. Quite a few example use this configuration, such as tilting mirror type VOAs. 6'/ #+,d'
